Hi !
What is meaning  of
"chunk_length_kb: sets the compression chunk size in kilobytes. "
?

It means that uncompressed sstable data is compressed to approximately 
chunk_length_kb and every read needs to read approximately chunk_length_kb and 
decompress it to read any value from compressed range  ?

Or it means approximately chunk_length_kb of sstable data is compressed and 
stored on disk, so similar values must be in chunk_length_kb range to make 
compression efficient  ?

Or something else ?

Thanks in advance, regards,
